2the sewage treatment process that quantity discharged is little, excess sludge is few.
In order to solve the problem, the technical solution adopted in the present invention is:
A kind of sewage treatment process, is characterized in that: comprise the steps, S1. is by the suspended substance in grid removal sewage and impurity; S2. under anaerobic, nutritive substance and carbonaceous gas is produced by the organism in the anaerobion degradation of sewage in active sludge, by the heavy metal in sorbing material absorption effluent and hardly degraded organic substance, by film, active sludge is separated with the water containing nutritive substance; The carbonaceous gas produced when S3. collecting degraded, utilizes the nutritive substance in carbonaceous gas and water to carry out microdisk electrode; S4. algae water is separated.
Further, a part of water and ferrous iron solution react after being separated by algae water, and reacted water backflow are reacted with sorbing material and anaerobion.
Further, sewage, in the process of reacting with sorbing material and anaerobion, adopts the mode of internal reflux to utilize sorbing material to wash away the surface of film.
Further, described sorbing material is preferably gac.
Based on a Sewage treatment systems for above-mentioned sewage treatment process, it is characterized in that: comprise the water inlet pipe, coarse rack, fine fack, gac anaerobic membrane treating pond, algae treating pond, algae settling tank, distributing well and the rising pipe that set gradually along sewage disposal direction; Comprise gac in described gac anaerobic membrane treating pond, containing the active sludge of anaerobion and film, gac anaerobic membrane treating pond is provided with the gas skirt for collecting carbonaceous gas, the carbonaceous gas that gas skirt is collected imports algae treating pond by airway; Described distributing well is connected with ferrous pond and gac anaerobic membrane treating pond successively by return line.
Further, described algae treating pond is provided with the gas recovery system for reclaiming inflammable gas.
Further, described algae settling tank is provided with the algae recovery system for reclaiming algae.
The invention has the beneficial effects as follows:
1. by film, active sludge is separated with containing the water of nutritive substance, improves activated sludge concentration, the surplus sludge volume reduced in follow-up sewage, consume energy low; By microdisk electrode draw degraded time produce carbonaceous gas and water in nutritive substance, both processed sewage, cultivated again micro-algae, resource recovery is high, reduces CO
2deng the quantity discharged of carbonaceous gas; Adsorb by sorbing material the heavy metal and hardly degraded organic substance that micro-algae can not absorb, while purifying waste water, ensure that the culture environment of micro-algae.
2. the water after the separation of algae water, dissolved organic matter may improve and contain H
2o
2, therefore a part of water and ferrous iron solution are reacted, improve the oxidation capacity of water, then the reacted water backflow with high oxidation ability is reacted with sorbing material and anaerobion, improve the efficiency of sewage disposal.
3. the surface that internal reflux utilizes sorbing material to wash away film can prevent film from blocking, and improves membrane flux and work-ing life.
4. gac has good absorption property, and treatment effect is good.
5. the carbonaceous gas being collected gac anaerobic membrane treating pond by gas skirt provides carbon source for algae treating pond, the gas collected on algae treating pond by gas recovery system can be used as combustion gas, micro-algae of being collected on algae settling tank by algae recovery system can be used as biofuel or protein formulation, useful matter in abundant recovery sewage treatment process, resource utilization is high.
Accompanying drawing explanation
Fig. 1 is the schema of sewage disposal of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As shown in Figure 1, based on a Sewage treatment systems for above-mentioned sewage treatment process, it is characterized in that: comprise the water inlet pipe, coarse rack, fine fack, gac anaerobic membrane treating pond, algae treating pond, algae settling tank, distributing well and the rising pipe that set gradually along sewage disposal direction; Comprise gac in described gac anaerobic membrane treating pond, containing the active sludge of anaerobion and film, gac anaerobic membrane treating pond is provided with the gas skirt for collecting carbonaceous gas, the carbonaceous gas that gas skirt is collected imports algae treating pond by airway; Described distributing well is connected with ferrous pond and gac anaerobic membrane treating pond successively by return line.
As shown in Figure 1, sewage treatment step of the present invention is:
1) collect treatment sewage, regulate impact load.
2) sewage enters from water inlet pipe, through coarse rack, utilizes coarse rack to remove suspended substance larger in sewage.
3) sewage is through fine fack, utilizes fine fack to remove suspended substance less in sewage.
4) sewage enters gac anaerobic membrane treating pond, under anaerobic, nutritive substance and carbonaceous gas is produced by the organism in the anaerobion degradation of sewage in active sludge, by gac, (gac has good absorption property, treatment effect is good) heavy metal in absorption effluent and hardly degraded organic substance (adsorb heavy metal and hardly degraded organic substance that micro-algae can not absorb, while purifying waste water, ensure that the culture environment of micro-algae), by film active sludge is separated with containing the water of nutritive substance and (improves activated sludge concentration, reduce the surplus sludge volume in follow-up sewage, consume energy low), carbonaceous gas (the CO mainly produced in microbiological anaerobic process produced when gac anaerobic membrane treating pond is degraded collected by gas skirt
2and CH
4deng gas), and import algae treating pond by airway.
Sewage, in the process of reacting with gac and anaerobion, adopts the mode of internal reflux to utilize gac to wash away the surface (preventing film from block, raising membrane flux and work-ing life) of film.
